Left- and centre-back are Wednesday's two most bare areas at present, assuming Lachman and Dielna are shown the door for good. A defensive-minded midfielder to replace Lopez (who could still return) and Semedo may be sought, though much will depend on how highly Carvalhal rates Melo. Another winger and striker are likely to feature on the Portuguese's shopping list, with the futures of Sougou and Bus uncertain.
